Seimone Augustus added 19 points for Minnesota (21-6), which won its eighth straight.

Brittney Griner scored 18 points for the Mercury (22-4), who lost for the first time since June 12.

Phoenix came in leading the league at nearly 50 percent shooting from the field, but was just 37 percent (25 for 68) against the Lynx - led by Diana Taurasi's 5-for-21 effort.

The teams have clinched the top two spots in the West and home-court advantage in the first round. Phoenix, which won the first two matchups, had its lead for the top seed cut to 1 1/2 games. The Lynx visit the Mercury on Aug. 9.
